Is it possible to regain a flat stomach after a second child without surgery? I am currently 7 mo. pregnant my child 2nd child. Had my 1st 4 years ago and went back to my prepregnancy size w/in 6 months...with a very flat stomach. I am wondering if a tummy tuck is an "inevitable" for women who have had 2 children or can you go back to flat tummy thru diet & exercise alone?
